Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Armed with a computer model in 1935, one could probably have written the exact same story on California drought as appears today in the Washington Post some 80 years ago, prompted by the very similar outlier temperatures of 1934 and 2014.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

Who Wants to Make Sarah Palin the Leader of the Republican Party?

Could it be the Washington Post? Bannered across the top of the Post’s op-ed page today is a piece titled “Copenhagen’s political science,” titularly authored by Sarah Palin. I’m delighted to see the Post publishing an op-ed critical of the questionable science behind the Copenhagen conference and the demands for massive regulations to deal with “climate change.”

But Sarah Palin? Of all the experts and political leaders a great newspaper might call on for a critical look at the science behind global warming, Sarah Palin?

What’s even more interesting is that the Post also ran an op-ed by Palin in July. But during this entire year, the Post has not run any op-eds by such credible and accomplished Republicans as Gov. Mitch Daniels; former governors Mitt Romney or Gary Johnson; Sen. John Thune; or indeed former governor Mike Huckabee, who might be Palin’s chief rival for the social-conservative vote. You might almost think the Post wanted Palin to be seen as a leader of Republicans.

I should note that during the past year the Post has run one op-ed each from John McCain, Bobby Jindal, Newt Gingrich, and Tim Pawlenty. (And for people who don’t read well, I should note that when I call the people above “credible and accomplished,” that’s not an endorsement for any political office.) Still, it’s the rare political leader who gets two Post op-eds in six months, and rarer still the Post op-eds by ex-governors who can’t name a newspaper that they read.
